Allan Cyril Brooks (February 15, 1869 Etawah – January 3, 1946) was an ornithologist and bird artist who lived in Canada. His father William Edwin Brooks had been a keen ornithologist in India but growing up in a farming household in Canada made his entry into the career of bird art much more difficult than for his contemporary Louis Agassiz Fuertes in the United States of America. His painting style was more impressionist with a greater emphasis on the habitat than on fine details of plumage. After Fuertes' death in a road accident, he was commissioned to complete the plates for Birds of Massachusetts.
